So, I got a new server which is DL 180G6 E5606 with 2* HP 2TB 6G 7.2K 3.5" LFF SAS DP Hard drives but BIOS do not detect them. Drives are properly mounted and I also tried to switch to RAID mode and boot but it didn't help. I've done lots of googling and I feel I am the only one with this issue. Maybe there is a bios patch? Unfortunately I am not near server anymore but far as I can remember it had BIOS from feb 2011. Any help is appreciated.

Now I've been doing even more research looks like it's because debian do not support DL180 G6 with Smart Array B110i SATA RAID out of the box, is there a way to make it work? I've seen few topics about this particular server and debian squeeze so atleast somebody got it installed well.
